Now keep it safe: three things

Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
Save this receipt to your camera roll.
Keep the receipt file too. The image is a handy copy; checking needs the file.
Email it to yourself.Email it to myself
Your mail app opens a draft. Attach your receipt image and receipt file. Don’t attach your photos or documents. Timevolt does not send it or know whether it was sent.

How to keep notes that hold up

Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.

Write it down straight away, on paper or in the box on a step.
Put the date, time and place at the top, and who you spoke to.
Use their words where you can; separate what you saw from what you were told.
Sign or initial a paper note, photograph it and add the photo.
Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.

Real cases: why the saved copy matters.

Real cases where dated records mattered. We don’t claim a time receipt would have changed the result.

British Columbia, Canada · 2023

Save the listing and prompt checks

A private car listing said there were no leaks, but the buyer found an oil leak the next day. The tribunal weighed the ad and prompt checks by a mechanic. A report says it ordered the seller to pay repair costs.

News report only; tribunal decision not checked. The finding concerned the leak claim, not a warranty for every used car.

Keep the garage report after a breakdown

A private car buyer said the seller had checked the car and said it was sound. After a breakdown, a garage report helped show problems were already there. A report says the buyer won, but extra costs and a penalty claim failed.

News report only; tribunal decision not checked. At least negligent misstatement was found, not a criminal ruling.

Proves / Doesn’t prove

Proves

A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.

Doesn’t prove

It does not prove identity, origin, truth, physical state, presence, consent, authority, sending, delivery, acceptance or outcome.

These are the bounds of a completed proof. The local tester does not establish any time. The chosen court, scheme or regulator decides what to accept.

Questions, answered plainly.

Your file stays on your device. During normal receipt creation, your device sends a randomized code made from its fingerprint, plus encrypted recovery data. It doesn't send the plain fingerprint or the random value that opens the code. Keep the original file and the complete receipt for checking. Privacy Policy.

Does an odometer photo replace the US disclosure?

No. For nonexempt transfers the federal rule specifies disclosure information and signatures in the title process.
